Karbonn reached a deal with Microsoft recently, company chairman Sudhir Hasija told the Times of India. “Microsoft has eased the regulations and is opening up its platform for other players. We signed the agreement two days ago and will launch a range of Windows phones in about three months,” he says.

Since last year, Microsoft has reportedly been open to the idea of dual-booting smartphones, in a bid to beef up its market share and challenge Android and iOS. It also seems like Microsoft is warming up to the idea of embracing more solidarity with Google’s Android OS. Last month, Nokia — whose device business Microsoft is in the process of acquiring — unveiled the Nokia X family of devices that run an operating system based on Android.
